REVEALED: The Secret Ingredient In Kit Kats

Mind-Blowing.

While we've had far too many with an afternoon cup of tea to count, we've never actually thought about what goes into them.

BBC Two Documentary Inside the Factory from 2015 has recently aired again and has received a lot of attention online.

According to theDaily Mail, presenter Gregg Wallace asked about the damaged KitKats that don't make it to our shelves and it was revealed that they're actually used again, as a factory worker states 'They go into re-work, where they're used for the fillings for the wafer.'

So basically, the hidden ingredient in KitKats is more KitKat.

@adamtaylorradio But what came first? The Kit Kat or the Kit Kat filling? My head is exploding!!
